What is the largest passenger plane?

The first airship designed to transport people could accommodate only 20 passengers, the Soviet aircraft "ANT-20" (which in 1934 was the largest in the world) - 80 passengers, "Boeing-747" can take on board 525 passengers, but the most large modern "Airbus-380" - 853 passengers, if both cabins are economy class!

This is a double-deck aircraft, its length is more than 70 meters, and its wingspan is almost 80. It can fly at a speed of 1000 kilometers per hour at an altitude of 13 kilometers, while it is economical and not very noisy.

Why do gene disorders appear only in males?

The hereditary information of an organism is contained in the chromosomes of its cells. Chromosomes are carriers of genes located in them (in a linear order). Each species of organisms has a unique and constant chromosome set. In somatic (non-sex) cells of higher plants and animals, the chromosome of each type is represented in a double number; a cell with two complete sets of chromosomes is called diploid.

Spermatozoa and eggs, in which each chromosome is represented only in the singular, are called haploid cells. The number of chromosomes in them is half that in somatic cells of the same organism. When an egg is fertilized by a sperm, the two haploid sets of chromosomes are combined, and thus their diploid number is restored.

About a century ago, one of the founders of genetics, Thomas Hunt Morgan (1866-1945) and his collaborators studied the mechanism of sex inheritance in Drosophila. They were able to find that the paired chromosomes of the females perfectly match each other, so all their eggs, receiving a chromosome from each pair, are identical. In males, in one of the four pairs, one of the chromosomes was normal (X-chromosome), and the other was shortened (Y-chromosome). This means that during the formation of spermatozoa, half of them receive the X chromosome, and the other half - the Y chromosome.

If a violation occurs in one of the female's genes located on the X chromosome, the paired gene corrects the situation. In males, this does not always happen, since the Y chromosome paired with the X chromosome contains much fewer genes. Therefore, gene disorders appear only in males.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

High-speed optical communication Li-Fi 15.06.2013

Li-Fi, short for Light Fidelity, is an optical wireless technology developed and presented by Harald Haas at the 2011 TED Talk. The French company Oledcomm announced that the first communication devices of its production, based on Li-Fi technology, will be available on the market next year.

Li-Fi technology works by binary modulating light from a special LED source. Modulation is carried out at a high frequency, and the transceiver itself in appearance is no different from an ordinary LED light bulb for household lighting.

Receiving sensors connected to computers or other digital electronic devices allow you to receive information when they are exposed to direct light from a Li-Fi source. This imposes some restrictions on the use of this technology, but in the end, such optical communication is somewhat safer than traditional Wi-Fi, the signals of which can be intercepted from anywhere within the range of the equipment. In order to intercept information transmitted via Li-Fi, an attacker will need to place his spy equipment literally on your lap, which can lead to serious difficulties for him.

In addition to the above, Li-Fi optical wireless technology can be used without restriction in places where the use of equipment that emits extraneous radio waves that may interfere with the normal operation of critical equipment is prohibited. Such places, of course, include intensive care wards of medical institutions, aircraft cabins and some other places.

At present, the information transfer rate that Li-Fi technology can provide is slightly higher than the speed of traditional Wi-Fi. Oledcomm representatives report that they have managed to obtain a stable information transfer rate of about 3 Gb / s, and a transfer rate of 10 Gb / s will be achieved in the very near future.
